ABSTRACT:
An electrophotographic copier having a hot roll fuser assembly. This assembly is slidably supported by a pair of rails. When the fuser assembly is locked into its fusing position, within the copier, it is relatively inaccessible for purposes of inspection, cleaning and/or jam clearance. In its withdrawn, inoperative position, a single manually operable jam clearance handle is operator accessible. Manual actuation of this handle, from a folded to an extended position, is effective to move both a sheet peeler or detach bar, and a sheet transport channel away from the fusing nip. When the handle is moved back to its folded position, the sheet detach bar and transport channel are accurately positioned, and locked in an operative position closely adjacent to the downstream side of the fusing nip, so as to aid in release of the sheet from the fusing nip, and to guide the sheet away from this nip.
